Hydrocarbon exploration and reservoir analysis

The Roslavl license block is one of the main assets of "RussNeft" company. Some particular perspectives of enhancing oil recovery are connected with this territory. The work objective was to define the perspectives of geological exploration, find new hydrocarbon deformational traps, and specify the geological structure of the already-known oil reservoirs in the Neocomian sediments, the Achimov strata, and Middle Jurassic sediments. The data analysis is necessary to create a new promising exploitation drilling program. The Roslavl license block is considered to be one of the most difficult and interesting areas in the sphere of hydrocarbon saturation perspectives from the quantitative aspects viewpoint. Different expectations on enhancing oil recovery in the Middle Ob oil and gas province of West Siberia are connected with this license block. Therefore, these perspectives were evaluated with the help of deep analysis of shooting data collected by seismic crews in different years, and the results of drilling. Different archival geological and geophysical evidence was analyzed to offer recommendations on the following geological exploration.
